Ho modificato il file config in /etc/cron-apt, adesso devo verificare che funzioni, cioè che alle 4 di ogni notte faccia l'update dei depositi security, che nel frattempo ho scorporato dal sources.list principale.
Ho utilizzato questo sito:
http://blog.pastoutafait.org/billets/Mise-%C3%A0-jour-automatique-avec-Cron-APT
Sembra che funzioni bene: oggi, 12 luglio 2012, ho trovato questo nella mail in /var/mail/francesco:

Dopo aver fatto questa modifica:
**Automatiser l'installation des mises à jour**
Pour installer automatiquement les mises à jour disponibles, il faut créer un fichier nommé "5-install" dans le répertoire "/etc/cron-apt/action.d/". Ajoutez la ligne suivante dans ce fichier :
dist-upgrade -y -o APT::Get::Show-Upgraded=true
Et voilà, les mises à jour seront installées automatiquement.
Notez que ce comportement n'est pas recommandé sur un serveur !
Il est préférable de faire les mises à jour à la main pour éviter toutes indisponibilités d'un service suite à un problème avec la nouvelles version installée.
Nel mio caso:
francesco@serverHP:/etc/cron-apt/action.d$ ll
